To review the most effective clinical approaches to disengage an impacted fetal head during cesarean delivery.

Women who undergo cesarean delivery of an infant with a deeply impacted head.

The "push" technique (from below) or the "pull" technique (reverse breech extraction).

Proper management of this clinical scenario can reduce maternal and perinatal morbidity and mortality.

Using an evidence-informed approach when an impacted fetal head is anticipated has the potential to reduce maternal and fetal complications and short- and long-term harm and their associated costs. Research into the value of simulation learning, regular labour assessments, and team preparedness for possible interventions will help inform quality care.

Randomized controlled trials had small sample sizes and were conducted in settings that limit the generalizability of their findings to the Canadian population.20 INTENDED USERS Intrapartum health care providers.Intersex individuals face human rights violations, discrimination, and stigmatization worldwide. Diagnosis in infants is uncommon, with between 1 in 2000 and 1 in 4500 infants born with ambiguous external genitalia sufficient to warrant genetic and endocrine studies. However, estimates of the actual proportion of the population falling under the broader umbrella of intersex, including sexual variation at the chromosomal, gonadal, hormonal, or genital level, are as high as 1.7%. As the rise of non-invasive prenatal screening (NIPS) capable of identifying intersex conditions at the fetal stage has increased the potential for prenatal detection, there is an urgent need for attention to the potential ethical challenges that may arise from earlier and more frequent detection. There has been growing attention in recent years to the harms faced by intersex individuals at the hands of the medical community. In the prenatal context, genetic counseling is one avenue by which prospective parents might be helped to understand the full spectrum of intersexuality and form realistic expectations for their children. However, best practices and medical policies to prevent stigmatization and discrimination against intersex individuals remain underdeveloped. There is presently a lack of Canadian-specific guidance or explicit legal protections for intersex individuals to guide health care providers in their relationship with these patients and their families. In this commentary, we argue that this gap calls for increased training for health care providers that incorporates the voices and concerns of the intersex community.
To explore barriers to academic activities that cardiovascular radiology-oriented radiology trainees face worldwide.

An international call for participation in an online survey was distributed via social media and radiological societies to radiology trainees. Questions covered barriers and involvement in academic activities during radiology training. Participants interested in cardiovascular radiology were selected for analysis with appropriate statistical methods.

Of the 892 respondents, 120 (13.5%) reported an interest in cardiovascular imaging. The majority (63.3%, 76/120) were from Europe and 57.5% (69/120) were men. There were gender discrepancies in academic involvement and in perceived gender-related barriers (perceived gender barrier in academic work between women and men 15/48 versus 5/69, respectively, p=0.001). The main barriers were lack of time, mentorship, and support. Most did not have protected academic time for research nor for teaching (61.7%, 74/120 and 57.5%, 69/120, respectively). Cy7 DiC18 cost Nonetheless, 40% (48/120) published as first authors, 77.5% (91/120) were involved academically in conferences, 71.7% (85/120) were positive about academic activities, 70.8% plan working in an academic setting, and 78.3% (94/120) would consider research training abroad.

Although the majority of respondents are positive about academic activities and plan to continue in the future, most do not have protected time. Lack of time, mentorship, and support were the main barriers. Fewer women declare involvement in academic work and output. There are significant perceived gender barriers to academic activities.

Intraoral scanning has benefits over conventional impression making, but whether scanning is sufficiently accurate for multiple implants is unclear.

The purpose of this invitro study was to compare the trueness of digital scans acquired by using intraoral scanners from a small range to a complete arch with the conventional impression technique and to determine the influence of 2 different evaluation methods (best-fit algorithm versus absolute linear deviation) on the outcomes of accuracy assessment.

A mandibular model with 8 implants (A-H) around an edentulous arch was used as the master model. Open-format standard tessellation language (STL) data sets (1 reference file from a highly accurate dental laboratory scanner, 10 files from an intraoral scanner, and 10 files from digitized conventional impressions at room temperature) were imported to a metrology software program, and 5 groups of scanning ranges (AB, FGH, CDEF, BCDEFG, and ABCDEFGH) were identified simulating different clinical situations. Two significant lower accuracy was found when larger areas were encountered (groups BCDEFG and ABCDEFGH). Use of the absolute linear deviation method resulted in a higher mean score of inaccuracy than that from the best-fit algorithm method in most situations.

Scanning or impression methods, ranges, and evaluation methods affected the dimensional accuracy (trueness) of scans or impressions with multiple implants. Digital scans had worse trueness values compared with those made with the conventional splinting open-tray technique when cross-arch implant impressions were acquired.
